Abstract
A secondary battery is disclosed. In one embodiment, the battery includes i) an electrode assembly and ii) first and second electrode tabs spaced apart from each other and extending from the electrode assembly, wherein the first and second electrode tabs have first and second outer surfaces, respectively. The battery may further include i) an electrolyte, ii) a movement prevention tape attached to at least a portion of at least one of the first and second outer surfaces, wherein at least part of the movement prevention tape is configured to become adhesive upon contacting the electrolyte and iii) a can accommodating the electrode assembly, electrode tabs and movement prevention tape.
Claims21
A secondary battery, comprising:
- an electrode assembly;
- first and second electrode tabs spaced apart from each other and extending from the electrode assembly, wherein the first and second electrode tabs have first and second outer surfaces, respectively;
- an electrolyte;
- a movement prevention tape attached to at least a portion of at least one of the first and second outer surfaces, wherein at least part of the movement prevention tape is configured to become adhesive upon contacting the electrolyte;
